Allmusic - "Everyone was expecting a lot from this group from the first time it was mentioned...For many reasons this just doesn't work...It seems like they all wrote their verses independently of one another, then rapped in whatever order they felt like it. There's no fluid feel...as a whole this definitely falls short of any of their solo work."
RapReviews - "...Most rap groups who made great albums needed guidance to make those great albums. The Criminalz definitely lack a mastermind to weld the three of them together and make them realize their synergies...There are almost no ad-libs, there's no interacting, it might as well be that these three never were in the same studio together..."
